You're certainly not the first person here who started out looking for a 4runner, and ended up with a pathfinder. They're easier to find, and more affordable to buy. Why keep it? Well, you have it... you may find it grows on you. We have a large base of members here that know these trucks, so they can help you find the usual troubles (as Slartibartfast mentioned some), and help you trouble shoot anything else that comes up.
Welcome & good luck!
